I respectfully disagree with you. I truly believe there is a high probability of this being the problem BBX has faced in Juma East (even if I have no proof or direct knowledge of that). And the very first reason of the null values in the batches of samples in 2015. It fits perfectly what is happening, and why all these delays. It also explains the inconsistency of the results and Drake's offer at such a low share price.
I also expect that in a few years that paper (and a lot of others, by the way) are more than "scientifically proven"; I expect that kind of papers to be well known and widely accepted.
For now, let's wait.
Have you all a great weekend,
The Alleged Drakeman
